The 200-4R is almost a direct replacement for a Powerglide or Turbo 350 tranny, some mods will be needed. The 700-R4 is a longer tranny, so you will have to shorten the driveshaft and a Turbo 400 crossmember will have to be used. It also will need to be relocated back a few inches on the frame rails.

the 2004-r is the Buick Grand National trans.and the 700r-4 is the more common GM trans. The 200 has similar gear ratios to a TH 350 where the 700 has a much lower 1st gear. If you currently have "high" gears likke a 3.08 you will love the 700. The 700 does require shortening your driveshaft where the 200 doesn't. There is a big debate on which trans. is better. Check out www.700r4.com and LET THE DEBATE BEGIN !

Note: A th-400 crossmember is not a bolt in with a 700r-4.

Sorry I was speaking about ALL automatics as "Slush Boxes" I just like four speeds more for street driven hotrods. I know everyone will attack me for this....but that's just because their car came with a slush box from the factory! Plus it only took me two trannys and three shift kits to set-up my current automatic....and I think I need to change the stall now too. I usually only buy 4-sp hotrods but this time I wavered.

Want '67 Vette Roadster next.....Automatics need not apply!

It's all about what you're after!! Spend a summer crusing around the SF bay area with our club or just sitting in traffic around any urban area and you'll be glad you have a "slush box"! Which unofficially really only refers to powerslides.... I mean powerglides.

Couldn't talk the little lady out of the auto?

When I was looking around at 2004r's the local shops convinced me to go with the 700r4. Most of the 2004r's they had dealt with were the lessor version that came in Monte Carlos , etc.

I'd go with the 700r4 unless you can find a 2004r from a GN or can afford one of beefier after market versions.

There is no doubt with the available parts and expertise that the 2004r can me made to withstand more abuse. But your wallet will definitely notice the difference.

Here is my .02.

The gear ratio for the TH200 is 2.75, 1.57, 1.1 and .67.

The gear ratio in the TH700 is 3.06, 1.63, 1.1 and .70.

There is a big space in ratio from 1st to 2nd on the 700 than in the 200. Which I have been told that could bog you down more on the 700 unless you really wind it up.

The other thing is with equal amount of money to spend "beefing up" either transmission you can get the same endurance. Accourding to some of the techs at Art Carr etc., they say that they race 900hp engines in front of their TH200s. Iv'e also been told that the 700 has a limit on how much HP you can push with it.

The 200 is smaller and is a direct bolt on for TH350s. The 700 is a lot bigger and I assume HEAVIER!

So, I guess when I get the $$$$ ill get a 200 for my 67. Hope this helps. MY .02.

if I were to put in an overdrive auto (other than wanting to slap a GV gear splitter on my TH350) I would go with the 200-4R for the reasons stated above... little easier installation, better gear ratios in my opinion, and about the same cost.

I understand where you guy's are coming from,but why did GM only use the 700r-4 in new Camaros, corvettes, and pick-ups? A 3.73 ratio would be the same 1st gear equivalant to a 4.56 with a TH-350. From my own experience 4.11's are to low for the 700r-4 I have owned and driven various pick-ups with the 700r-4 and a 3.73 gear and I was happy with them. Of course they mostly had a 31" tire also !!

Heck I'm not even going to wast my time trying to talk her out of it. Just wasted time when her mind is made up. I do guess I will go with 200R4 unless to many people advise against it though. I plan on buying a beefed up one why get cheap now.

Bruce who frequents this board on occassion builds some beefy 200-4R transmissions if you are running a high-horse application. His screen name is "WE4" If you aren't beating on it too much, www.tpiperformance.com told me a few years back that their 200 will handle a typical 450 horse motor.

I would do some shopping before making the decision. Installation from a stick to auto is going to be the same no matter which you decide on. You know what kind of power you have and how the car is driver. Talk to some tranny builders. Most will specialize in one or the other but work on both. Get prices on what they specialize in matched to withstand your engine spec's.

The part brought up about what cars got what tranny is still playing in my mind. I don't think a turbo 6 would have liked the 1,2 gear spread of a 700r4 but a street v8 shouldn't be out of it's power range with it.

Either way if it makes mama happy it should make you happy!!

Dennis, dont you have a 700r4 in your Camaro?
this topic couldn't have come along at a better time for me as I'm about to get my TH350 replaced and wasn't sure which of these two options to choose. I have 3.73 rear-end gears and was wondering if they are going to be a bit much with the first gear of the 700. Are you happy with how yours drives?
BTW when's the next meeting of the club, I think its about time I made the effort to come and meet you guys seeing as I live so close by.

Dennis, Why did you go with the 700R4? I have beed intouch with Steve Holmes from Bow Tie Overdrives and from what I gather its 6 on way half a dozen the other. I have a hard enough time making these descisions. How much work was it to install? I dont want to permanatly change anything so I can return the car back to stock. Just like I have the original heads but I'm running Edelbrock Aluminum on it now. If I do go 700R4 it will use a custom rear crossmeber as to not drill any holes. But that also requries a new or modified driveline. Does anyone out there use a Auxiliary cool without the radiator unit? He advised against it, But if I do that than I have to get a different radiator. Right now A Laqte model Mustang Cobra with a auto is starting to look good. As I see it the only thing I have figured out is No turbo 350.
Mike
